During the Lego Minstorm Experiment several factors were tested. The test results were as follows:
Mass (KG) | Power Level Related to Force | Time (s) | Height (m) | Acceleration (RPM/s) | Acceleration due to Gravity | mass(gravity)height | Power | |
83 | 0.25 | 75 | 1.981 | 0.27 | 40.855908 | 9.8 | 0.6615 | 0.333922261 |
69 | 0.21 | 75 | 1.595 | 0.27 | 53.458594 | 9.8 | 0.55566 | 0.348376176 |
70 | 0.17 | 75 | 1.45 | 0.27 | 60.166468 | 9.8 | 0.44982 | 0.37236755 |
97 | 0.17 | 100 | 1.208 | 0.27 | 105.304226 | 9.8 | 0.44982 | 0.37236755 |
84 | 0.17 | 50 | 3.326 | 0.27 | 16.648171 | 9.8 | 0.44982 | 0.135243536 |
As clear through the link above, the results were as expected because when graphing the information it was presented linearly.
To gather this information we used a lego windstorm pulley, that had a rope with attached weights for different masses. With the pulley system the effects of differing weights and differing power levels were tested. As the load on the pulley got lighter the acceleration (RPM/s) increased, which is to be expected. When testing the different power levels the weights remained at a consistent 0.17 kg, and as expected again the acceleration increased with increasing power levels.
If the experiment was to be repeated, it would be beneficial to have an automatic stop on the pulley system, to limit the amount of human interference that occurs and potentially effects the system.
Awesome blog but i would like to see some graphs that would help understanding the experiments
